OVEN.

To all whom 'itmy concern: A

Be it known that l, WILLIAM J; BEST, a ycitizen of the United States,and ares'ident of Detroit, in the county of llVayne and State ofMichigan, have invented a new and Improved Oven, of which the followingis a specificati-ion.

This invention relates to' gas ranges and its objectis to provide arange oven so constructed that the heated air and productsA ofcoinbustionare admitted thereto in practieally'the vSame quantity. andproportion through' both sides and escape therefrom r in practically thesaine" proportion through openings at the yback and front ofthe bot,-

-tom, thus insuring a practically even teinperature throughout the ovenand giving InV the accompanying drawing, Figure 1 is agfront elevationof a= gas range embody# ing this invention.v Fig. 2 isa vertical transverse section o n the line 2 2 of Fig.

F 3 is a vertical longitudinal sectionon the lineS-,f of 'Fig'. 2.` Fig.4 is a horizontal longitudinal section on t-he line 4 4: of Fig. 42.Fig. 5 is a vertical transverse sec tion on tlie'line of Fig. 4. Fig. isa partial horizontal transverse section of a range slightly different.in details 'of ennstin'ctioii fronfthztt shown in Fig. 4. Fig. 7

is a vertical Y'cioss"section on the lineff'HT of Fig. 5. f

Similar reference characters refer `to like parts throughout. theseveralv views.

The drawing shows a range' having the well knowntop 1 'andfiiel pipe As'this fuel-pipe forms no part of this invention it is omitted in all butFig. 1. ln thisspecitication the exterior shellv will be tei-ined the,casing and the interior shelLwill, betermed the oven. The casing isformed of aback 3,' sides et and 5, a bottoni 6, and front 7 'The top 1is preferably supportediby theback and sides ofthe casing. `The ovenhas'a top 8,

preferably of'several 'thicknesses' of sheet metal separated by a'sheetof asbestos or other 'poor heat coi'ducting material, and the casingsides 4 and 5 are preferably similarly formed. rThe back 9 ofthe oven is-separated from the back of the casing and connects toits sides andbottoni. Plates 10 extend from the bottom ofthe casing to the. sideedges of the oven bottom 11, which specification of Lener raient.

has perforations 12 near its back and front for the-escape of theheating medium.

Extendingbetween the front 7 of the casing and back plate 9 of the ovento forni the sides of the oven are plates 11 and 15, having inwardlyextending flanges 16 and 17, to support racks or plates to receive thefood to be cooked. Between the plates and the sides of the casing aredelict-.tor plates 18, preferably formed with down turned flanges 19.The front Iplate of the casing joins the'top and bottom of the oven, andthe opening in this plate is normally closed by the door 2O.y which maybe provided with a glass plate 21. K

Extending into the space below the. oven is a fuel pipe 23 havingbranches 21 which' connect to t-lie rearwardly extendingl burner tubes25 near the bottoms of the side fines. Small windows 26 in the frontadmitof the burning of the gas being observed. Air for the burners canenter through openings in the bottom of the easing shown in `Fig. 2.A

The operation of the oven is as follows. rllhe burners being lighted andthe door closed. the heated air and products of combustion will passupward` a pnrtion strikingy against the plates 1S and beine; deflectedinwzirdlv between the bottoni plate Ll of the 'ouen and the flange 1T ateach side. The other portion will pass up and into the oven` a portionthrough between the plates 14 and 15 and t/he remainder abovethe plates14. lThe hot. gases which enter below thc detlector plates 1S will canseeddies in the oven, resulting` in an even temperature. '.lho gasesfinally escape through the. holes l2 in the bottoni plate and enter thespace below ythe oven. A pipe 2Q extends into this space `and has aninlet openingpreferablyr in its upper side and' preferably near themiddle of the bottoni of the oven. The gases will therefore pass inpractically equal quantiities through the holes 12 at the back and at"of one plate 18 at each side over the burner.

type of grating may be employed. I Instead tubes 25, 'a plurality ofplates Oamay be employed as shown in Fig. 6. Many other changes in thedetails of construction may be made by those skilled in the art Withoutdepartingfrom the spirit ofv my invention. Having now explained myimprovements, what. I claim as my. invention and desire to secure byLetters Patent is 1. The combination of a casing, anoven Within thecasing and spaced therefrom,

said oven having perforations in its bottom near each end, a doorforming the front of the oren, the sides of the oven having longitudinalopenings toadmit the products ot combustion, burners 'at the lower edgesof the sides ot' the oven, deflector plates positioned over the burnersto cause a portion of the products of combustion to enter the loren atthe bottoms of its` sides, and a pipe extending to the middle of thebottom of -the oven to carry away the products of combustion whichescape yfrom the oven through sides of the oren having openings near thebottom and top, and delector plates mount-v ed above the openings nearthe bottom of the oven and having down-turned edges to compel a portionof the products of combustion to enter the oven near its bottom.

4. 'lhe combination of a casing, an oven within the casing and spacedtherefrom at its sides, burners at the bottom of the spaces between thesides of the oven and casing, the sides of the oven having openings atthe bottom of the oven and above the same, dtiector plates of lesslength than said oven extending between the sides of the oven and thecasingjust above the lower openings to compel a portion of thelproduotsof combustion to enter the oven at the bottom and permitting theremainder to ascend and enter through the upper openings.

In testimonyY whereof, I have signed this specication in the presence oftwo subscribing witnesses. l
